In PC field, there is a famous Moore's law, common explanation is computer chip performance every 18 months will double, evidence of Moore's prospective. Moore's law in the PC industry to gallop after forty years, seems to be on the cellphone again punches. In this year's global mobile communications conference (MWC), each big brand mobile phone manufacturer haste to release the new products, new products and the first key words is one of the four nuclear.
And some analysts view, the "nuclear arms race" come some early, the cell phone battery technology has not yet breakthrough, power consumption is a big problem fatal weakness, in the mobile phone applications, and there are no four nuclear to support.
News background
Magging issues.it four nuclear mobile phones
Four nuclear cell phone camp including huawei, zte, HTC, LG, etc. Huawei launched Ascend D quad mobile phone, launch Android 4.0 operating system, USES is independent design haisi huawei four processors. LG Optimus by 4 X HD, zte Era, HTC's One X are using the company's Tegra3 NVIDIA four processors.
Four nuclear mobile phone no doubt have become the MWC conference window, but also become the focus of dispute. Although belong to four nuclear camp, but this several manufacturers but not harmonious, huawei and LG have said their new product is the world's first four nuclear andros mobile phones. MWC during the exhibition, huawei terminals chairman YuChengDong (the Po) is still in the Po to another enterprise "not naming names criticism", says "the enterprise four smart phone and no nuclear development mature."
And the other not push four nuclear product manufacturers is to LG, HTC and manufacturers launched four nuclear smartphone show his disdain and calm, Microsoft (the Po) Windows Phone departments of the truth: "four nuclear mobile Phone competition is ridiculous, not was necessary completely. Like digital camera pixel war that, mobile Phone manufacturer is only playing with Numbers game." Microsoft's the personage says, nokia (the Po) Lumia 800 etc Windows Phone mobile phones don't need four nuclear processor can quickly running applications. In addition to Microsoft, SONY mobile departments also say four processors is not suitable for smart phones.
The battery into the biggest obstacles
Smart phone replace function machine is an inevitable trend, people use contentedly smartphone, but found a little regret can't make up for, and that is the power consumption smartphone is too big, mobile phone standby time is short, to meet the needs of sustainable use.
Smart phones have great power consumption, and four processors running on the basis of complex applications will speed up power consumption. "The battery is still no breakthrough, most mononuclear cell phone is usually restricted to 1 ~ 2 day, if is four nuclear, if the battery problem is solved, so only half a day. Even if the processor mature, but the battery is still a global problem." The horizon research consultancy group senior telecom analyst CengTao said. And, now users buy mobile phone not only pay attention to performance, also pay more attention to appearance, frivolous become main melody. This creates conflict, manufacturers how to put greater capacity of the battery and more low energy consumption system into the fine thin body, this is a huge challenge.
SONY mobile department at MWC Stephen Sneeden during congress said it is not suitable for push four main factor lies in nuclear cell phone battery, "SONY in the next year in the cellphone won't before four processors. When we feel performance and efficiency of the cells, we will match to join the ranks of the four nuclear mobile phone. Because now we don't think this is the match."
A cool person told reporters that they may be in the second half of this year launched four nuclear mobile phone, "but before that, must will solve the problem of power."
Four nuclear too luxury?
PC processors have stepped into the nuclear age 16, but the overwhelming majority of users are still dual-core, because they feel dual-core computers have satisfied the demand of himself, of course, if 16 nuclear computer and dual-core computer as cheap that nature is another story. His computer is still dual-core, cell phone that four nuclear, what is it? Isn't it too luxury?
Luxury is on one hand on the selling price, CengTao estimates, four nuclear mobile phone price will not less than 3000 yuan, "for high-end brand of four nuclear mobile phone, price can be as much as four or." In addition to the class user, won't have too many customers to choose four nuclear mobile phone, especially in the smartphone has greatly reduced the threshold of today, even though these entry-level smartphone, now of the configuration has also upgraded substantially.
More extravagant point is that at present most intelligent mobile phone applications are still not make full use of the processor core bring function. Dual-core, and even mobile phones to meet people demand in single-core still and ease, four nuclear mobile phone and not so necessary to appear. "I don't know now what mobile phone applications need four nuclear to deal with, can't come up with it. Just like PC, now of people mainstream application does not need so high processor", CengTao said.
More than foreign industry comes to put forward, four nuclear cellular phone now seem to be some redundant. And Tegra3 launched four processors NVIDIA company responded that the Tegra 3 four processors only in application to call to start the four processor core. The rest of the time is a low power consumption of the kernel in operation. But this and bring another problem, if in the most time need only a kernel, why not stick mononuclear or dual-core processor?
"Nuclear war" another attempt to?
The processor, operating system, display screen, the program, battery... Mobile phone industry chain in all aspects, as long as one place there short board, will not give customers with better user experience, oneself also is to have a as.
CengTao said, now manufacturers in treating the four nuclear cell phone into two groups: the conservative and extremism. Conservatives such as Microsoft, SONY, they hope to relevant industrial chain can coordinated development, especially the battery this short board can get "extended", such as basic mature industry chain again after using four nuclear technology. Radical hope that through the four nuclear this quite can attract the attention of the public new technology as a killer, in global market competition to get the upper hand, and even take a risk for this. "But if mass to the market, because the battery standby problems by the consumers, this to the manufacturer for collective as is a risk."
These manufacturers launched four nuclear cell phone in addition factors, may be to counter strong apple. Apple iPhone success was not relying on top of the hardware configuration, but the hardware, the system, the software 3 person perfect together. But iPhone 4 S is already dual-core, so some cell phone manufacturers hope rob in the next generation of apple products before release, in hardware configuration and the gap between the open apple, and on the market in a larger slice of the cake.
